Yeah it does remind me of Animusic/Pipedream, except it's of a much lower level of 3D graphics performance since NV1 was a very early, very low-end 3D accelerator without any geometry processing / T&L. Whereas the Radeon 9700 was a highend GPU that came out 7 years later.

"Demo videos sent to me by an engineer who indicated they were shipped with NV1 powered Diamond Edge 3d multimedia board. (1996-1997)

A collection siggraph convention animation entries stretching from about 1984 to the early 90's. Most of these pieces were developed to showcase some inovation in 3D animation. The notable developments being displayed are motion scripting, texture maps, reflectance mapping and perhaps even ray tracing but I'd have to look a little more closley. Diamond Edge had nothing to do with these other than perhaps packaging them with their product."
